Adiabatic Process
Easychemistry
In an adiabatic process, which of the following is true?
Select the correct option:
Solution
Incorrect! Answer:
Q = 0
An Adiabatic Process is defined as one in which there is no heat exchange between the system and its surroundings.
- Condition: q=0
- This typically happens when the system is perfectly insulated or if the process occurs so rapidly that heat has no time to flow.
- From the first law: ΔU=q−w⟹ΔU=−w.
- If the gas expands (w>0), its internal energy and temperature must decrease.
